Eligibility Criteria
You may qualify if:
- Male or female patients between 18 and 55 years of age, inclusive;
- Clinical diagnosis of schizophrenia or schizoaffective disorder according to Diagnostic and Statistical Manual of Mental Disorders (DSM-5);
- Clinically stable and free from acute exacerbation of psychosis for at least 3 months prior to Screening;
- Clinical Global Impression - Severity (CGI-S) score ≤ 3 at Screening and prior to dosing on Day 1;
- Body mass index (BMI) between 18.0 and 38.0 kg/m2, inclusive at Screening, and a minimum body weight of 50 kg at Screening.
You may not qualify if:
- History of psychiatric condition other than schizophrenia that, in the Investigator's opinion, may be detrimental to participation in the study;
- Any suicidal ideation or wish to be dead within the past 6 months of Screening, any suicide attempt within the past 2 years prior to Screening, or any current concern for the patient's safety based on the Columbia-Suicide Severity Rating Scale (C-SSRS) (excluding self-injurious, non-suicidal behavior), and/or Investigator assessment that the patient is a safety risk to him/herself or others;
- Clinically significant abnormality within 2 years of Screening that in the Investigator's opinion may place the patient at risk or interfere with study outcome variables;
- Has a QT interval corrected for heart rate using Fridericia formula \> 450 msec in males or \> 470 msec in females, or evidence of clinically significant bundle branch blocks on ECG at Screening.
